N. Y., A CORPORATION OF DELAWARE UNIVERSAL J OIN T Application filed April 13,

prised elements assembled and connected by means 'oftrunnion hearings in such fashion that the relativelv' movable parts are cona rings. In order to provide a universal joint which is formed of elements connected through anti-friction bearings, the presentinvention has been designed and an object thereof is to provide a universal joint, whereinthe friction of the joint is greatly reduced "over joints now available.

A further object of the invention is to provide a universal joint having the relatively movable elements thereof connected through "I anti-friction bearings.

A further object of the invention is to pror Vide a joint of the above character, wherein the joint seal is of a materially improved form.

Further objects, not specifically enumerated above, will be apparent as the invention is described in greater detail in connection with the accompanying drawings, wherein:

Figure 1 is a view in section, taken through the longitudinal axis and on the plane indicated by the line 11 in Figure 2, looking in the direction of the arrows and showing a universal joint constructed in accordance with the present invention.

Figure 2 is a view in section, taken on line 22 of Figure 1, and looking in the direction of the arrows.

Figure 3 is a view similar to Figure 2, showing a modified form of joint.

Figure 1 is an enlarged detailed view in section, showing an improved trunnion mounting for a universal joint constructed in accordance with the present invention.

Referring to the above drawings, and parof universal joints of the type now ter which has been ex- 1931. Serial No. 529,595.

ticularly Fi ures 1 and 2, driving and driven shafts are s 1own at and 11. The shaft 10 is keyed to a. plate 12 to which a housing 13 is bolted by means of bolts 14. .This housing is formed with an opening 15 and is provided with aligned journal bearings 16 which receive trunnion pins 17. In the form of the invention shown in Figures 1 and 2, the trunnion pins 17 are formed as bolts having heads 18 and nuts 19. The bolts thus secure races 20 in position and mount anti-friction bearings 21 upon which a driving ring 22 is journaled. Transversely to the axis of the pins 17, the driving'ring is formed with aligned apertures 23 within which anti-friction bearings 24 are secured. Bearings 24 thus serveas trunnion bearings for receiving arms 25 which are formed upon a sleeve 26. The arms 25 are formed with extensions 25' of reduced diameter upon which the antifriction bearings 24 are mounted, pins 27 serving to secure the hearings in position.

Shaft 11 is splined, as indicated at 28, and the sleeve 26 is formed with grooves within which splines 28 are received. In this fashion,

relative axial movement of the shaft 11 with respect to the housing 13 is permitted.

A metallic shield 29 is formed ofspherical section and provided witha sleeve 30 which snugly fits over the sleeve 26. Sealing material 31 is provided within an annular struckup portion 32 of the sleeve 30 to effect the sealing of the joint between the shield29 and sleeve 26. A flange 33 is carried by the sleeve 26 and serves as a seat against which spring 31 engages, the other end of the spring engagmg the spherical shield 29. The spring 34 thus seats. the shield 29 against an annular sealing washer 35, carried by the housing 13. In order that lubricant may be supplied to the sleeve 26, a. fitting 36 is provided thereon and-the space between the shaft 11 and sleeve 26 is sealed by means of sealing washers 37 which are secured in position by means of cap sleeves 38. r

In the construction shown in Figure 3, the driving ring is formed of two sections, split upon an axis perpendicular to the axis of the joint, and secured together by means of bolts 40. One of the sections is indicated at 41 2 1 mouse and is shown as adapted to be secured to a cooperating section to mount the anti-friction bearin in position. This form of joint greatly facilitates the assembly of the mechanism, as well as the inspection and repair thereof.

In the construction shown in Figure 4, trunnion pins 50 are shown as provided with tapering heads 51 received in tapering recesses 52 formed in the housing 13. Nuts 53 I are provided to seat the trunnion pinsand secure the anti-friction bearings 21 in position. Y

It will'be seen that the foregoin construction provides a universal joint wiereof the I friction is greatly reduced over devices of this kind which are now available. The rogvisionrof'a structure which is adapte to 1 receive anti-friction bearing as shown herevin renders the 'oint highly eflicient and imparts greater li e'thereto. -While the invention has been described .with specific reference to the accompanying drawings, it is not to be limited, save as defined in the appended claim.

I, claim as m invention: I A universal Joint for driving and driven members comprising a housing carried by one of'the members, adriving rin ,opposed ins so having tapered heads mounte in tapere recesses in" the housing, the walls of'the heads and recesses tapering from a maximum diameter adjacent the exterior of the housing to a minimum diameter adjacent the interior 86 walls thereof, anti -frictionbearings on the pins, means to secure the bearings to the pins, and anti-friction bearings between the ring and driven member upon an axis at right I an les to the axis of the first bearings.
